Zusammenfassung:Fatalities caused by sharp and pointed instruments, especially screwdrivers, are not frequently observed in the United States. The shape of the screwdriver tip generally determines the resulting wounds that can range from linear, to rectangular or cross‐shaped, often reflecting common screwdriver head shapes. Recognizing such patterns is crucial, as they can aid in identifying the potential weapon used in the crime. In the reported case, an adult male was found dead in his living room surrounded by a pool of blood, with multiple injuries. At autopsy, the pattern of penetration was consistent with that of a six‐point star (Torx) screwdriver, which has never been reported as a deadly weapon in the literature before. A Torx screwdriver has a blunt head, resulting in hybrid injuries with both penetrating and blunt force features. Because of its rigid structure and narrow tip, a Torx screwdriver may forcefully penetrate the skin, soft tissues, and bone, causing severe injuries to the deep organs. The case highlights the importance for the forensic pathologist to examine and recognize atypical penetrating wounds for the identification and location of rare weapons. High‐definition graphic documentation of the injuries allows thorough examination and comparison of injuries with potential weapons. When the weapon is not retrieved, detailed injury descriptions guide investigations toward searching for a screwdriver, improving the chances of identifying the weapon used to commit the crime.
